Vulnerability from variot
Buffer overflow in ngx_http_mp4_module.c in the ngx_http_mp4_module module in nginx 1.0.7 through 1.0.14 and 1.1.3 through 1.1.18, when the mp4 directive is used, allows remote attackers to cause a denial of service (memory overwrite) or possibly execute arbitrary code via a crafted MP4 file. nginx is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Attackers may leverage this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions. nginx versions 1.1.3 through 1.1.18 and 1.0.7 through 1.0.14 are vulnerable; other versions may also be affected. nginx is a lightweight web server/reverse proxy server and email (IMAP/POP3) proxy server developed by Russian programmer Igor Sysoev. Failure to do so will result in a denial of service. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201206-07
